/**
 * The <code>CSSCharsetRule</code> interface represents a @charset rule in a CSS style sheet. The
 * value of the <code>encoding</code> attribute does not affect the encoding of text data in the DOM
 * objects; this encoding is always UTF-16. After a stylesheet is loaded, the value of the
 * <code>encoding</code> attribute is the value found in the <code>@charset</code> rule. If there
 * was no <code>@charset</code> in the original document, then no <code>CSSCharsetRule</code> is
 * created. The value of the <code>encoding</code> attribute may also be used as a hint for the
 * encoding used on serialization of the style sheet. <p> The value of the @charset rule (and
 * therefore of the <code>CSSCharsetRule</code>) may not correspond to the encoding the document
 * actually came in; character encoding information e.g. in an HTTP header, has priority (see CSS
 * document representation) but this is not reflected in the <code>CSSCharsetRule</code>. <p>See
 * also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113'>Document Object Model
 * (DOM) Level 2 Style Specification</a>.
